Weather Rewind -- July 7-13, 2013

Temperatures averaged 3.1 degrees above average last week -- with "just" one 90 degree day in the hopper as temperatures on Sunday reached 94 (tying the year's high so far). Between the constant humidity, save for Friday morning locally, and the thunder threat that permeated the region for most of the week, it's a bit of a tired act of sorts to have both of these going at you at the same time...but alas, we continue to trudge along.

Humidity was arguably the bigger weather story of the week -- we had varying intervals of tropical showers and storms nearly every afternoon around the Delaware Valley, picking up a trace or more of rain at Philadelphia each day. The brunt of rains and storms occurred on Friday as an upper level disturbance interacted with a frontal boundary to produce heavy rains over Delaware and Cape May that pivoted northwest into the Philadelphia metro for the dinner hour and Friday evening. Thunderstorms that developed early on Friday morning dropped two to three inches of rain across Delaware County but the evening rains added another inch or more to that...of course, it paled in comparison to the buckets of rain that fell in Southern Delaware.

The streak of days where the thermometer fails to go below 70 at any point is still rolling at 20 as of Saturday night, with another week likely ahead to tack on and make a run at the 26 day record from 1876 and 1995.
